2. Description of the Prior Art

In recent years, in specific areas, such as exhibition venues, shoppingmalls, museums, playgrounds, campuses, etc., location-based servicesusing beacon signals have emerged for users of mobile data processingapparatuses.

However, in these specific areas, due to crowded beacon signaltransmitting apparatuses, or due to on-site environmental factors, it isoften difficult for the user's mobile data processing apparatus toquickly determine the selected beacon signal transmitting apparatus fromnumerous beacon signal transmitting apparatuses. Even a wrong beaconsignal sending apparatus is often determined as the selected beaconsignal transmitting apparatus from numerous beacon signal transmittingapparatuses. It also makes users feel bad about location-based servicesin these specific areas.

In addition, because mobile data processing apparatuses of differentbrands or different types of mobile data processing apparatuses of thesame brand may have different sensitivity in receiving signals, itresults in different numbers of beacon signals received by differentbrands and different types of mobile data processing apparatuses at thesame position. At present, there is no multimedia transmission systemand method which can intelligently adjust the reception threshold of themobile data processing apparatus to receive the beacon signal, so thatthe mobile data processing apparatus can quickly determine the selectedbeacon signal transmitting apparatus.
